Abstract
Biosensor technology has undergone transformative advancements in recent decades, enabling rapid, sensitive, and selective detection of a wide range of biological and chemical analytes. Contemporary biosensors integrate multidisciplinary innovations in materials science, nanotechnology, microfluidics, and molecular biology to achieve enhanced performance, scalability, and real-time monitoring capabilities. This review provides a comprehensive assessment of current biosensor systems, including enzyme-based, immunological, nucleic acid, microbial, fluorescent, and nanomaterial-assisted platforms. Their operational principles, fabrication strategies, and performance metrics are discussed in detail. The growing applications of biosensors in healthcare diagnostics, food quality monitoring, environmental surveillance, bioprocess control, and biodefense are critically evaluated. Recent breakthroughs in genetically encoded sensors, wearable biosensing technologies, and point-of-care testing devices highlight the expanding horizon of the field. The review concludes by outlining future directions and technological challenges that must be addressed to further enhance biosensor sensitivity, integration, and commercialization. Overall, contemporary biosensor systems demonstrate immense potential to revolutionize global health, industrial processing, and environmental sustainability.
